Ground, in order to meet the Electro Magnetic Compatibility (EMC of electrical system or equipment：Electromagnetic compatibilty) in terms of
Existing requirement, it is known to following filter：In DC network, which filters out the high frequency letter being coupled in DC channel
Number (so-called EMC filters).
Especially in electric vehicle, the problem is that, it is necessary to accumulator (for example, battery unit) and motor it
Between busbar (busbar) on transmission high current (for example, the up to electric current of 500A).Therefore, busbar overheats in order to prevent, busbar
There must be sizable cross section (for example, in cm2In the range of).Electric component (especially capacitor) must be with these mothers
Line connects, so as to filter out High-frequency Interference.In addition, the transition impedance (Ohmic resistance, the parasitic electricity that are generated when connecting capacitor
Sense) it must be as small as possible.
So far, the connection of electric filter component (especially capacitor) is by welding the join domain of capacitor
Be connected on busbar (especially previously passed suitable material processing (for example, drilling or milling) and what is prepared be used for welding procedure
Bus-bar area on) come what is carried out, so that the join domain being formed thinly and busbar can only fused.On the one hand, this is consumed
When and it is of high cost, but on the other hand, error is easy, the reason is that the quality of electrical contact is largely dependent upon phase can occur
When the quality being welded to connect changed greatly.
Invention content
Based on this, the purpose of the present invention is to propose to one kind can by the time efficiently and it is cost-effective in a manner of manufacture and also
It can realize the filter apparatus of the reliable electric contact of filter part.
Described problem is solved by the feature of independent claims 1.Preferred embodiment is the master of dependent claims
Topic.The manufacturing method of filter apparatus is the theme of independent claims 14.

When being clamped in Carrier element 4 between two busbares 2,3, these contact tongues 8.2 can upspring in the side of horizontal aligument
Property deformation or correspondingly deform so that contact tongue 8.2 pass through restoring force be pressed against busbar 2,3.Conductor path region 4.2 as a result,
With contact site 8 ', 8 " between there is low ohm transition resistance, as a result, formed capacitor 5,6 and busbar 2,3 low ohm company
It connects, that is, do not use soldering connection or be welded to connect.Other than contact tongue, other contacts for being constituted with spring-like fashion
Regional variety is also possible, for example, the contact area 8.1 of the contact element with helical spring form.
Using printed circuit board 4.1, contact site 8 ', 8 " can be by being for example soldered to conductor path region

The fixation of the free end of Carrier element 4.As depicted in figs. 1 and 2, one or more holders 10 can be used, so as to fixed female
Line 2,3.
Particularly, as can be seen in Figure 3, contact tongue 8.2 can turn relative to x-y plane at least partly
It is dynamic, that is, particularly, around the rotary shaft rotation for being parallel to y-axis extension.The fringe region of contact tongue 8.2 is relative to connecing as a result,
Remaining region for touching tongue piece 8.2 projects upwards, and whereby when busbar 2,3 to be clamped each other, busbar 2,3 may be implemented on these sides
At edge region against.Contact site 8,8 can also be improved as a result, ' with the electrical contact between busbar 2,3.
Contact site 8 ', 8 " region in, gasket 9 can be provided with.This gasket 9 can be surrounded for example and be connect accordingly
Contact portion 8 ', 8 " frame-like form extend or this gasket 9 can it is only point-by-point or partially around contact site 8 ', 8 " set
It sets.It can select the height of gasket 9 so that the deformation of contact tongue 8.2 is restricted, that is, contact tongue 8.2 is not to pass through folder
It holds busbar 2,3 and is completely against on Carrier element 4, but at least part of interval is kept with it (referring to Fig. 3).
In the case where component 7 is formed by the shell constituted in the form of a cup, this shell can use suitable cast
Material is poured into a mould, for example, epoxy resin or similar material.Thus, it is possible to protective condenser 5,6 and Carrier element area
The influence of 4a, 4b (if applicable) from moisture and vibration.
